Performance enhancing drugs (PED) are a serious problem in the NFL, but that didn't stop Kyle Long from making a joke about being randomly selected for testing.

According to a photo posted to his Twitter account, Long says his massive arms are the result of hardcore gaming -- not PEDs.

Long is a huge man at 6-foot-6 and 328 pounds, but him being confident enough to make a light of drug testing on social media tells us that it's all natural. His father, Howie Long -- a member of the Pro Football Hall of Fame -- must have taught him always to be a principled player.
